Repoint embedded PSC to a external PSC

Hi All,

I have a lab environment deployed with a VCSA v6.5 and an external PSC. I need to add a secondary vCenter server v6.5 deployed on windows server 2012 with an embedded PSC to join the external PSC and enable linked mode between 2 lab environments.

As far as I know to reconfigure embedded PSC to an external one I need to have a replication in between them and replication can only configure during deployment of external PSC.

So since I already have my external PSC deployed how can I achieve this task. Kindly help me out.

Thanks in advance.
